MAN'UFACTURING COMPANY, OF TRENTON, NEW JERSEY, A CORPQRATION OF NEW JERSEY (701\T1Q'IE1C'JPIO1\`l' FOB. WATER CLOSET COMBINATIONS Application filed November 10, 1931. Serial No. 574,054.

This invention relates to a water closet combination comprising a bowl and tank, wherein the latter rests upon and is entirely supported by a rearwardly ext-ending hous- 5 ing, in which the spur and other connections prising similar clamping devices 'that pass through slotted openings in the bottom of the tank and also through registering openings in the deck of the housing, thebottom of the tank being forned interiorly with means for guarding and concealing parts of the clamping devices that are disposed within the tank and at the same time preventing the fiushing water from escaping through said bottom' openings. By the provision of the leak-preventing means, the several clamping devices may be applied to the tank bottom without any packings, and the said devices may be attached to the tanks by the manufacturer, thus facilitating the ready and quick assembling of the bowl and tank either before or during the installing of the combinations. And a further object is to provide clamping means of this class that may be applied and adjusted without tools, by simply manipulating the several parts of said securing means.

I attain these objects by the means set forth in the detailed description which follows and as illustrated in the accompanying drawing, in which- Figure 1 is a top plan view of the water closet bowl, showing a rearwardly extending shelf, which is formed with a depending 'housing for the spud and other connections.

Fig. 2 is a partial rear end elevation and a partial vertical cross-section, the latter taken on line 2-2 of Fig. 3, showing the internal Construction and arrangement of the adjacent parts of the tank and bowl; also showing the several connecting means in position to rigidly clamp the tank to the bowl. Fig. 3 is a broken side-elevation of the bowl and tank. Fig. 4: is a horizontal section taken on line 4--4 of Fig. 2, showing the arrangement of the bottom of the tank, and the spud and other connections in the clamping positions. And

Fig. 5 is a broken vertical cross-section showing the clamping-devices of Fig. 2 on an enlarged scale, also showing the mushroom shields to prevent the fiushing water. from escaping through the slots of the tank bottom.

In the drawing, 2 represents the closet bowl, which may be surmounted by an ordinary flushing rim, as 3, the latter being extended a considerable distance rearwardly of the bowl proper to form a shelf 3'. This extended portion is formed with a relatively large integral housing, as 3a, that lies below the plane of the shelf, the said housing having a relativelyelarge opening 3?) at its rear end, and the plane top of the shelf 3" being cut away to form a corresponding upwardly facing opening 30 to loosely receive the usual slip spud connections, as 4, that comprise a part of the flushing means, as best shown in Fig. 2. Wi'thin the housingBa, is formed an integral hollow lip or spud support 5, that communicates for flushing purposes with the rim 3, as indicated by the dotted arrow in Fig. 3. The lip 5 has a plane top provided with a circular opening 5' that coincides with the opening 30 and receives the lower end of the connection 4. 6 represents the flush tank which may follow any of the usual constructions, whose bottom 6' is formed with a central discharge opening, as 6a, that aligns axially with the opening 5' of the lip and receives the` top end of the connection 4, as shown in Fig. 2. In addition to the more or less stout and rigid slip connection 4., which tends, when tightened up, to draw and hold the tank in intimate contact with the shelf 3', the said shelf is provided with similar oblong longitudinal' slots, as 3d, to receive bolts, as 7, thatpass downwardly through registering oblong slots `(Sa-that are formed in the bottom 6' of the tank, for rigidly and in- By this arrangement, the spud connections are relieved of all dangerous strains and may be removed and replaced or adjusted without disturbing the bolts 7 and related parts. The top ends of the bolts 7 are formed with T- heads, as 7', that are slightly smaller than the slots 60 and are of greater length than the dependently clamping the tank to the shelf 3'.

breadth'of said slots, so that when the heads 7 are inserted through the slots 66 and afterwards rotated a quarter turn, the heads assume a position at right angles to said slots (see Figs. 2, 4 and 5), and cannot be withdrawn from the tank until again brought into exact registry with the openings 60. The bolts 7, in practice, are first applied to the bottom 6' of the tank in the manner last described, after which plain washers 8, split spring washers 8', and nuts 8a are fitted there- -to and tightened up for rigidly holding the bolts against turning or being accidentally released from the tank. This workof ap- 'plying the bolts 7 may be performed by the 'forcing plates 9' and finally wing-nuts 9a.`

These wing-nuts may be tightene d sufliciently by hand to securely hold the tanks on the bowls, as shown.

In order to avoid all danger of leakage f the flushing water through the slots 60, as well as to shield the clamping bolts 7 from injurious contact with the water, the bottom,

6' of the tank is formed with hollow semispherical or mushroom-like guards d having a diameter greater than the length of the slots 60, in which the heads of the bolts are disposed. This Construction entirely eliminates all packing in connection with'the sai-d bolts and openings, and reduces the hazard of leakageto the single opening 6a that receives the spud connection 4. By referring to Figs. 2

" and 5, it will be understood that the heads 7' shown, afl`ordsa relatively were cast en bloc.

of the bolts may be rotated' freely'within the guards Gd. By disposing the bolts 7 in line with the spud4 and sp'acin these parts, as

%road clamping range which renders the'combined bowl and tank practically as strong as though the outfit The present clamping ;devices are extremely simple and strong, and may be readily and 'quickly applied and removed without the use of any tools, and besides, by the provision of the novel mushroom ards d, the bolts 7 require no packing. hen the adjustable part s of the clamps' are properly tightened, in order to eflect the complete assembly of the tanks and bowls, the combination may be transported, installed or moved from one lo- ,cation to another, as one part. This cannot be done in the case of the older water 'closet outfits wherein the tanks are mounted upon the walls of the toilets and are only connected housing, said bowl andsaid tank having registering slots, of means for clamping the tank to the bowl comprising T-shaped bolts adapted to extend downwardly through the bottom of the tank and said deck, nuts disposed in the slots of the housing to secure g the bolts to the tank, and nuts engaging the bolts beneath the said deck to prevent separation of the tank and bowl.
